To all ruf/1.0m t may concern.'

Be it known that I, BLA ZsARNAY, a cltizen l of Hungary, residing at Belleville, county of aeroplanes capable of Essex, and State of New JerseyLhave invented certain new and useful Improvements in Aeroplane's, of which the following is a specification.

The' present invention relates to improvements in aeroplanes, as for instance described in my copending application, Serial No.

330,756, and it is the principal object of the invention to provide a motive system for propelling the aeroplane by compressed air.

A further object of the invention is the provision of means for lifting the aeroplane by a lifting propeller rotated by compressed air and for vpropelling the aeroplane when a certain height has been reached by means of compressed air, the carrying power of which has been increased by an auxiliary air supply.

These and other objects of the invention,

` which will become more fully apparent as the description thereof proceeds, are obtained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure l is a side view of an aeroplane constructed according to the present invention, and

Fig. 2 is a front elevation of the same, partly in section, on line 2-2 of Fig. 1.

Referring to the drawing in detail, the numeral 10 designates a chassis upon which is attached a motor 11 operating the pumps4 12 at the front, and air compressors 13 at the rear of the chassis.

A turbine 14 is located in a central position in the chassis and is driven by the air delivered to the same from the compressors 13 4through a pipe 15 provided with a valve 16 rIhis turbine rotates the propeller shaft 17 carrying at its upper end the lifting propeller 18 and below said propeller the shaft 17 carries a stationary housing 19 from which pipes 2O branch off which are connected by the pipes 21 controlled by valves 22 with the pumps 12.

Specication ofjLetters Patent.' l

application filed March 5, 19a-1.

Fatented Nov. 15, 1921.,

Serial No. 449,389.

The compressed air from the casing of the turbine lll is exhausted through pipes 23 rotating with the shaft 17, against the under face of the aeroplane wing 2d braced against the chassis by the braces 25.

A turbine 26 is driven by compressed air from the compressor 13 fed to the turbine through pipe 27 controlled by a valve 28. rIhis turbine rotates a horizontal propeller shaft 29, carrying on its outer' end a driving propeller 30. I

A stationary body 31 in which the shaft 29 rotates receives the compressed air exhausted from theturbine casing and the same is carried through a pipe 32, controlled by a valve 33 to the pump12 from which it is pumped through pipes 34 and 35 against the lower face of the lifting wing 24, and

through pipe 36 under the tail piece 37 of the aeroplane.

It will be clear that any number of lifting and driving propellers may be provided with a corresponding number of turbines and connections with the air compressors which compressors as well as their pumps may be selected in any number to suit the purpose.

The customary landing and starting wheels 38 are provided and secured to the lower part of the chassis.

It will be apparent that changes may be made in the general arrangement and construction of the minor details of my invention, without deviating from the scope and spirit thereof.

What I claim as new and desire to secure by Letters Patent of the United States, is

1. An aeroplane of the character described comprising a chassis carrying a motor, compressors and pumps operated by said motor, lifting and driving propellers, turbines for operating said propellers, lvalve controlled pipe conduits connecting said compressors with said turbines, means for guiding the surplus of compressed air from said turbines to the pumps, lifting wings, and pipe conduits for guiding said surplus of compressed air underneath of said wings to increase the carrying power of the aeroplane.

2. In an aeroplane of the character described, comprislng in combination with its wings lifting and driving propellers and their shafts and motor operated air compressors and pumps, turbines on the shafts of said lifting and driving propellers, pipes for conducting air from said compressors to said turbines, stationary housings on the shafts for said lifting and driving propellers', valve controlled pipes connecting said housings with the compressor pumps, and pipes rotating with the shaft for said lifting propellers for exhausting the surplus of oompressed air against the underside of said 10 wings, substantially as described.

In testimony whereof I have alixedz my signature.
